The dynamic teenager joined from Premier League giants Manchester City and has already made one international appearance for Norway, in a 3-2 win over Iceland.

“I’ve been here for a year now, and nothing makes me happier than signing a new contract at the club to stay even longer,” Samuelsen told the official West Ham website.

“I’ve really enjoyed the year I’ve had at the club so far and I want to build on that. It’s just been one upward journey so far, and I’m really happy to sign a new deal and hopefully I can push on and do even better.”

Samuelsen made his senior West Ham bow before he earned a loan move to Peterborough last November, where he scored two goals in 20 appearances.

Following the new contract, Samuelsen eyes are fixed on another loan move to the Football League, as he seeks out more competitive first-team football.

“This season, I think it’s either going to be another loan or first team football for me at West Ham,” he added to the Hammers website. “I really enjoyed my time at Peterborough United last season and to have another spell playing good football on loan somewhere would be great.

“Both options would be good for me, but one is tougher to achieve than the other! Whatever happens for me this year, I’ll go into it 100 per cent committed. My long-term goal is to get into the West Ham first team XI.”
